I had the discussion with my GF yesterday! what should be awesome is to have playlist by Shows order. For exemple every week night we are watching the same shows in the same order like it will be on TV. So it could be awesome to create preset of show list which playing the episodes in the same order. Exemple
1 - Big Bang theory (one episode)
2 - Brookly Nine Nine (2 episodes)
3 - Stranger things (1 episode)
and when you start it play the 4 first unseen episodes.
More over, I don’t know if you can do that, but I you name your preset “evening playlist”, enable the way to start it from Siri. And we will be in a magic world!
